Description
The Yealink T53 is the entry model of the T5 Business series. Its backlit 3.7-inch display (360 x 160 pixels) tilts to stay readable at any viewing angle or lighting. It handles 12 SIP accounts on 8 programmable keys, a 1,000-contact phonebook, hot desking, call park and call pickup. Optima HD voice combines wideband, full duplex, echo cancellation and an adaptive jitter buffer; Acoustic Shield technology uses several microphones to isolate the voice from background noise. The USB port serves call recording, a USB wireless headset, the EXP50 expansion module or the optional Wi-Fi and Bluetooth adapters; the DD10K DECT dongle pairs up to 4 cordless handsets with it. Two Gigabit ports with PoE, the RJ9 headset port with optional EHS40 and wall mounting complete this phone, managed through the web interface or auto-provisioning.

Use and tips
The T53 equips offices that handle a steady volume of calls and want a large display without moving to color: administration, accounting, practice, technical support. Its 12 accounts and 8 programmable keys cover colleague monitoring and speed dials; the EXP50 module adds 60 more if needed. It registers on any SIP-compatible IP PBX and deploys through auto-provisioning. On a PoE switch, no power adapter is needed; otherwise add the 5 V / 1.2 A power supply sold separately. For built-in Wi-Fi and Bluetooth, see the T53W.
